Hello Amol,

You can try this:

$find('RadGrid1').get_detailTables()[index].get_selectedItems().length

Where "index" is the index of the detail table in RadGrid's detail table collection.

i want to find out number of rows or checkboxes selected in javascript for

DetailTables

[Veli]

Hi Amol,

The javascript provided below finds the number of selected items in the DetailTables that are visible (rendered). For example:

$find('RadGrid1').get_detailTables()[0].get_selectedItems().length

The code above finds the number of items selected in the first detail table in RadGrid, which means the highest expanded detail table in the current page of RadGrid. I hope this clarification is helpful.

i have implement your code
it is giving following error
Object doesn't support this property or method

After getting object of DetailTables.
DetailTables have not any propert or method (like .selectedRows) that will give me selected rows

i am using following code to get object of DetailTables

grid.MasterTableView.DetailTables[0]

Hi Amol,

The described methods are the member methods of the older version of RadGrid for ASP.NET client object.The provided sample code refers to the latest RadGrid for ASP.NET AJAX Framework, which this ticket has been marked for. If you are using the older RadGrid for ASP.NET, then you would transform your code to:

window['<%= RadGrid1.ClientID %>'].DetailTablesCollection[0].SelectedRows

Please note that the DetailTablesCollection has objects inside only if the actual detail tables are generated, which means that it would have length 0 if no item is expanded on ServerOnDemand detail table binding. If your HierarchyLoadMode is set to "Client", however, you will have all your detail tables available in the collection even before expanding.

Hello Everybody,
                      
                         i am just one step behind solution.when i expand detailsTable
i got proper result using following code.

if

(grid.DetailTablesCollection[0].SelectedRows.length > 0 || grid.MasterTableView.SelectedRows.length > 0){
alert("Delete all selected Record's?"); }else{alert("Please Select at least one Record");return false;}

But when i don't exand detailsTable and go with same code it gives me following error. i set HierarchyLoadMode to "Client".

Microsoft JScript runtime error: 'grid.DetailTablesCollection.0.SelectedRows' is null or not an object

how can i know is detailsTable is exanded or not .If i got any boolean value,it will be my solution. 


Thanks in Advance

Hi Amol,

Please try the following:

if(grid.MasterTableView.SelectedRows.length > 0)
{
    if (grid.DetailtablesCollection[0].SelectedRows != null && grid.DetailtablesCollection[0].SelectedRows.length > 0)
    {
        alert("Delete all selected Record's?");
    }
    else
    }
        alert("Please Select at least one Record");return false;
    }
}
else
{
    alert("Please Select at least one Record");return false;
}

This is to make sure the SelectedRows collection of the detail tables is generated.

Best wishes,

Hello Amol,

If you sent HierarchyLoadMode="Client" for RadGrid, your DetailTablesCollection should not be null even if there are no detail tables shown (all items are collapsed). On the other hand, if you need to use server hierarchy loading, your DetailTablesCollection will hold only the shown detail tables. In this case you can check if the item is expanded using the grid.MasterTableView.Rows[itemIndex].Expanded property.
